Abstract
L'invention concerne des systèmes et des procédés à codage de canal source commun pour modulation multiporteuse (MCM). Selon certaines variantes, le procédé décrit comporte les étapes suivantes: estimation de rapport gain/bruit de canal (CGNR) en fonction d'un secteur de fréquences ; détermination des paramètres MCM qui permettent de réduire au minimum la distorsion d'un ou plusieurs signaux de télémesure ; production d'un signal de communications sur la base des paramètres MCM, et transmission de ce signal via un canal de communications. On peut déterminer les paramètres MCM en réduisant au minimum une mesure de distorsion de signal de télémesure sous réserve d'une valeur de CGNR et d'une contrainte de puissance d'émission. Enfin, les paramètres MCM peuvent refléter différents besoins de fidélité en cas de transmission de plusieurs signaux de télémesure.
